If the lifting object falls during the operation of the jib crane, it will pose a great threat to safety. Therefore, we must understand the causes of the crane’s heavy weight falling and strengthen the prevention to prevent the occurrence of safety accidents.floor mounted jib crane for sale
1.Unsafe behavior of people
Human behavior is affected by various factors such as physical, psychological and comprehensive quality. It is characterized by unskilled operational skills, lack of necessary safety education and training; non-driver operation, undocumented employment; violation of rules and regulations, bad operational habits; judgment Operation errors, command signals are not clear, lifting drivers and cranes are not coordinated, and human biological rhythms are in the “three high areas”. In short, poor safety awareness and low operational skills are the main causes of accidents.
2.Security management defects
Management includes leadership safety awareness level; implementation of crane management, inspection and regular safety performance inspection; safety education and training for relevant personnel; special training for lifting workers, regulation of crane safety operation and establishment of illegal reward and punishment system And the accident emergency plan, the lack of effective monitoring and management of the periodic inspection of lifting equipment and lifting aids. Any negligence and inadequacy in safety management is one of the important reasons for lifting casualties.port crane
Unfavorable environments that exceed safety limits or hygienic standards, such as high-dust, high-temperature, high-humidity, low-temperature, high-noise, windy days, poor lighting, etc., will be distracting and directly affect the operator’s ability to respond. The stability of the technology, the chances of misoperation and illegal operation increase, resulting in accidents. In addition, the poor working environment will also cause the crane system itself to reduce the function or even accelerate the failure of the zero (structure) parts. One of the safety factors.
4.Unsafe state of the jib crane
The first is the risk caused by the irregular design of the jib crane, such as overload protection failure, insufficient balance axle strength, no anti-decoupling device, unreasonable selection of rigging rigging, etc., followed by manufacturing defects and installation defects, such as improper selection, The processing quality is not good, so that the equipment with hidden dangers is put into use. A lot of problems exist in the use of the link, for example, failure to replace the scrapped parts in time, lack of necessary safety protection, poor maintenance and operation, and even cause movement out of control, parts or Structural damage, irregular safety performance inspection, etc. In short, defects in any part of design, manufacture, light crane installation, use and inspection may bring serious consequences of the fall of the hook hanger. The essence of the crane (design, manufacture, installation) Safety is the basic condition for ensuring the safety of lifting operations.
The efficiency of the three-dimensional parking equipment is an important indicator for testing the products of the three-dimensional garage(parking system equipment) company. It also directly affects the operation efficiency of a parking lot. The efficiency of the three-dimensional garage access vehicle is high. The traffic volume is higher, and the income of the operating owners is higher.
Nowadays, in the bustling metropolis, large parking lots abound, and many large parking lots use stereo garages to solve parking difficulties. In these large three-dimensional garages, the traffic volume is large and the number of cars is large. What can be done to improve the efficiency of the three-dimensional garage?
1.as far as possible to design a wider driving lane, so that users can easily travel in the stereo parking garage, without the situation of traffic jams. In foreign countries, the driving lane can generally be designed as a one-way street to avoid traffic jams.
2.as much as possible to design a three-dimensional garage parking space, you can use one to two, make full use of the design, use the upper and lower layers to effectively increase the parking space, greatly improve the space utilization of the three-dimensional garage. In a city with a large flow of people, this is a good way to accommodate a large number of cars in a block.
3.Increase the entrance and exit of the three-dimensional garage. It is obvious that the more entrances and exits of the three-dimensional garage, the more convenient it is to enter and exit the vehicle, thereby improving the efficiency of accessing the vehicle and reducing the waiting time of the user.
4.as far as possible to design a large three-dimensional garage parking size, convenient for users to park on the stereo garage car board, this kind of multi-vehicle garage products. If the size of the design is too small, a slightly larger vehicle will be difficult to park on the loading plate of the three-dimensional garage, thereby increasing the difficulty of parking the user and reducing the parking efficiency.bridge crane for sale
5.Use as many friendly and humanized three-dimensional garage parking induction signs as possible. In a large three-dimensional garage, we can use different colors to distinguish different three-dimensional garage parking areas, to facilitate user memory and quick access to the vehicle.
The small crane is the abbreviation of Small Crane. It is usually a special type of small crane (usually lifting weight less than 12 tons) installed on the chassis of small cars and agricultural vehicles. Widely used in construction sites, industrial and mining enterprises, stations, terminals, electricity, postal, urban construction, gardens, paving bridges and other fields.light crane manufacturer
KBK rigid small crane:
Closed rails, modular production and assembly. To ensure reliable and stable quality, the lifting capacity can be up to 3200kg, and the scope of application is wide. It is especially suitable for modern production lines such as machining, assembly and warehousing. Its characteristics are summarized as follows:
Reliable, stable, accurate, cost-effective
The track is made of high-strength steel once cold-rolled to avoid deformation of the secondary weld. The closed design of the track effectively prevents the occurrence of dust on the rolling surface, thereby reducing the resistance and wear of the small wheel and the track. Make it more flexible and extend its service life.
Simple structure design, reducing failure rate; smooth wheel contact surface and unique wheel design, ensuring low running resistance, low noise; lighter manual operation, low overall power, low energy consumption
The rigid connection and the unique guide wheel design ensure that the main beam will not be inclined or swayed under the condition of no load, thus ensuring the best positioning of the load.
The high-strength track and the expandable truss structure design make it unnecessary to increase the I-beam suspension as a whole, thereby reducing the overall weight, lifting capacity of up to 2000kg, economic and environmental protection. In particular, the optimization of the truss structure can make the interval up to 9m, greatly reducing the number of columns or supports, reducing space interference, and making the layout of the plant beautiful and simple.
Adaptable, precise layout
Modular production, modular combination installation, can be accurately designed according to your actual needs, reducing equipment waste. All kinds of standard modules can be connected by bolts, which can be modified according to the changing production needs.
The optimized structural design provides self-supporting column suspension type beamless ultra-low clearance and other installation methods according to the customer’s existing plant structure and space requirements. Stainless steel rails are available for clean spaces and food grade rails for different operating conditions.
